Please help identify this axle!!!

spin the tire and count the times the driveshaft turns.. you want to spin the tire like 5 times so it is important to pay attention to how many times the driveshaft rotates......mark both with a piece of tape.

also you can save your gear oil just dump it in a clean container....take all the guess work out of it.

Man so I’m doing that wrong?!? lol WTH!?!?

The video said count the driveshaft, spin the tire….i got something like 1.8-1.9….was a full 2 rotations of the driveshaft by the time the tire was back to its start point. So that’s wrong?

So, the more rotations you do of the tire (while the opposite side is held stationary), the more accurate you can get. So, with say, 10 tire rotations, you should get 20.5 pinion rotations for a 4.10 gear ratio. The formula is multiply the pinion rotations by 2 (since you are rotating only one tire), then divide by the number of tire rotations (x1 for one tire rotation, x2 for two tire rotations, etc).

Yeah so I took this video….i understand more equates to more accuracy but this should be pretty straightforward yes???

So I reprogrammed to 3:73 and then did 4:10…my digital Speedo was off by 2mph (faster) with both ratios…so that doesn’t help haha.

So I never use ai but figured I’d put this in just to see…with the steel knuckles, the information about it being off a 2022 jlur, the FAD delete, rotating the wheel and counting about 1.8 driveshaft turns per 1 tire rotation and now this….I’m thinking pretty confident that these are 3.73 gears…

interesting...this what my sticker says and I have 4.10's. maybe someone else will check and see what theirs say.

So I put that number into the ol ai machine….

I believe the tags you guys are showing are shipping labels put on DANA prior to shipping. That doesn't look like MOPAR part number.

The 5-digit number after the P plus the 3 larger digits and the 2-letter code is a Mopar number.

True. But when I ran the numbers on one of the online sellers, no joy.

I find the OP's axle online at a lot of the mopar stores, but not with the AO code on the end (highest I found was AM). None of the stores say much about it other than "front axle assembly" and "locking differential". They don't identify what it fits or the gear ratio or anything.

Yes that’s the same issue I kept running into…odd right.

 

[stretch-bsn]

I think this has been pretty much figured out (sans pulling the diff cover but figured I’d share more evidence of why I’m pretty sure it’s a 392

When I was changing shocks the other day I took a picture of the rear brake caliper. I’m guessing they wouldn’t stamp “392” on anything other than a 392 yeah?
